摘要
介绍了根据CATIA软件对VBA(VisualBasicforApplication)的支持 ,利用VBscript脚本语言开发飞机翼面的造型设计程序的方法。并对外形较复杂的导流片 ,利用数学方法计算生成其截面控制点 ,利用程序读取控制点坐标 ,直接在CATIA软件曲面设计环境中 ,自动生成各翼肋剖面的Spline曲线 ,然后采用CATIA高级曲面的“Loft”命令完成飞机翼面的造型设计。
A method used to design an aircraft wing surface by means of program is introduced in this paper. The program is developed by VBA (Visual Basic for Application) on the base of CATIA software. For a baffle with complex profile, the control points of section are calculated by a mathematical function. The splines of former sections are created automatically in the generative shape design of CATIA using VBA program which read direct a series of coordinates of control points, finally, a aircraft wing shape is generated by 'loft' command of CATIA.
